The basic equation for total distance traveled is: d = (V_initital)(t) + (0.5)a(t²) d = displacement of the object (distance traveled) V_initial = initial velocity t = time a = acceleration Step 1: Determine the information from the word problem you can plug into the equation. d = unknown (this is what we are solving for) t = 4 seconds a = 9.8 m/s² The object in this scenario is falling, so the acting force is gravity. The acceleration for any object moving under the sole influence of gravity (i.e. hanging from a spring) is the gravitational constant which is 9.8 m/s² so the equation is now: V = 0 Since the object starts from rest, the initial velocity is 0. Step 2: Solve for the distance traveled. 11ec0fda_997e_9714_a67f_bf0837699a51_NR0004_00
